Model CHQ-WSB2/WL is an EN54-23 compliant addressable loop powered Wall Sounder Beacon innovatively designed to provide a range of tones and volumes with a maximum output of up to 102dB(A) (±2dB(A)) with low current consumption. The unit features an integral beacon within the horn utilising high intensity LED technology and is designed to fit to the Standard Base (YBO-R/3(RED)) or the Isolator Base (YBO-R/SCI(RED)). The sounder is IP rated to IP21 for internal use but it can be made weatherproof by utilising the WS2-WPK Weatherproof Kit, which consists of a specialised back box and gasket set. Also incorporates an auto shutdown mode which allows the user to set a fixed time within which the sounder will operate, before automatically silencing itself, ideal for minimising noise pollution. Dependent on control panel compatibility.
